What the FY2027 request buys

Verbatim from the R-2A exhibit for project MD31 of PE 0603890C. This is the budget justification's own description of work that has not happened yet — the one thing no other level of the budget carries.

FY2027 planned work

- Define and begin implementation of governance required to develop, employ and sustain the cloud-based Digital M&S capability. - Establish initial digital framework and simulation environment capability as a baseline for performance assessment. - Begin refactoring legacy Frameworks, Core Truth Models and element M&S representations into micro-service structured and containerized capabilities in the Cloud environment. - Initiate development of Element models/representations for inclusion in the cloud-based M&S Enterprise Simulation. - Initiate modifications of threat modeling capabilities in support of future missile defense architectures in the Cloud. - Initiate development and begin integration of M&S framework, representations of new architecture participants, and Core Truth Models required for software integration, test and assessment in the Cloud. - Initiate development and begin implementation of Data Management, Analysis Support, configuration management, and run-execution applications to enable Digital M&S capabilities in the Cloud. - Conduct initial integration and test events in the Cloud to support missile defense capability deliveries and verify the performance of the initial Digital M&S capability.

FY2026 to FY2027 change

Increase from FY 2026 to FY 2027 provides for development of a cloud-based Digital M&S capability to support rapid development, integration, test, and assessment of complex future missile defense architectures.

Money

Three years, and no five-year plan

An R-2A activity publishes the prior year, the current year and the budget year. The FYDP outyears exist at project and program-element level and are deliberately absent here rather than inferred. Estimate types are colored and never summed into one figure.

This activity is 81% of project MD31's FY2027 request and 7.8% of PE 0603890C's. In the request year the activities under a project sum to it exactly; in the current year they under-cover it in about 9% of cases, so an activity's delta can legitimately exceed its parent's and the two must not be compared row to row.
